+## Simple hash verification
+
+When secure boot is not used, a simple hash can be appended at the end of the
+image for integrity check. Applications should be built with
+`chip_simple_hash_verification=1`.
+
+## Writing the SSBL
+
+Before writing the SSBL, it it recommanded to fully erase the internal flash.
+
+Using DK6Programmer utility from Windows:
+
+```
+DK6Programmer.exe -V 5 -P 1000000 -s <COM_PORT> -e Flash
+```
+
+Using `dk6prog` from `SPSDK`:
+
+```
+$ dk6prog listdev
+This is an experimental utility. Use with caution!
+
+List of available devices:
+DEVICE ID: DN038ZH3, VID: 0x403, PID: 0x6015, Serial number: DN038ZH3, Description: DK6 Carrier Board, Address: 9, Backend: Backend.PYFTDI
+$ dk6prog -d DN038ZH3 erase 0 0x9de00
+
+This is an experimental utility. Use with caution!
+
+Erasing memory  [####################################]  100%
+```
+
+`chip-k32w0x-ssbl.bin` must be written at address 0 in the internal flash:
+
+Using DK6Programmer utility from Windows:
+
+```
+DK6Programmer.exe -V2 -s <COM_PORT> -P 1000000 -Y -p FLASH@0x00="chip-k32w0x-ssbl.bin"
+```
+
+Using `dk6prog` from `SPSDK`:
+
+```
+$ dk6prog -d DN038ZH3 write 0 ~/path/to/bin/chip-k32w0x-ssbl.bin
+
+This is an experimental utility. Use with caution!
+
+Writing memory  [####################################]  100%
+Written 7890 bytes to memory ID 0 at address 0x0
+```
+
+### Writing the PSECT
+
+This is the list of all supported partitions:
+
+```
+0000000010000000 : SSBL partition
+
+    00000000 -----------> Start Address
+    1000 ---------------> 0x0010 Number of 512-bytes pages
+    00 -----------------> 0x00 Bootable flag
+    00 -----------------> 0x00 Image type (0x00 = SSBL)
+
+00400000c9040101: Application partition
+
+    00400000 -----------> 0x00004000 Start Address
+    c904 ---------------> 0x04c9 Number of 512-bytes pages
+    01 -----------------> 0x01 Bootable flag
+    01 -----------------> 0x01 Image type (0x01 = Application)
+
+00000010800000fe: Ext Flash text partition
+
+    00000010 -----------> 0x10000000 Start Address (external flash)
+    8000 ---------------> 0x0080 Number of 512-bytes pages
+    00 -----------------> 0x00 Bootable flag
+    fe -----------------> 0xFE Image type (0xFE = Ext Flash text)
+
+00000110300200fc : OTA Image partition
+
+    00000110 -----------> 0x10010000 Start Address
+    3002----------------> 0x0230 Number of 512-bytes pages
+    00 -----------------> 0x00 Bootable flag
+    fc -----------------> 0xFC Image type (0xFC = OTA partition)
+
+00000510100000fd: NVM partition
+
+    00000510 -----------> 0x10050000 Start Address
+    1000 ---------------> 0x0010 Number of 512-bytes pages
+    00 -----------------> 0x00 Bootable flag
+    fd -----------------> 0xFD Image type (0xFD = NVM partition)
+```
+
+First, image directory 0 (SSBL partition) must be written:
+
+Using DK6Programmer utility from Windows:
+
+```
+DK6Programmer.exe -V5 -s <COM port> -P 1000000 -w image_dir_0=0000000010000000
+```
+
+Using `dk6prog` from `SPSDK`:
+
+```
+$ dk6prog -d DN038ZH3 write 0x160 [[0000000010000000]] 8 PSECT
+
+This is an experimental utility. Use with caution!
+
+Writing memory  [####################################]  100%
+Written 8 bytes to memory ID PSECT at address 0x160
+```
+
+Here is the interpretation of the fields:
+
+```
+00000000 -> start address 0x00000000
+1000     -> size = 0x0010 pages of 512-bytes (= 8kB)
+00       -> not bootable (only used by the SSBL to support SSBL update)
+00       -> SSBL Image Type
+```
+
+Second, image directory 1 (application partition) must be written:
+
+Using DK6Programmer utility from Windows:
+
+```
+DK6Programmer.exe -V5 -s <COM port> -P 1000000 -w image_dir_1=00400000C9040101
+```
+
+Using `dk6prog` from `SPSDK`:
+
+```
+$ dk6prog -d DN038ZH3 write 0x168 [[00400000C9040101]] 8 PSECT
+
+This is an experimental utility. Use with caution!
+
+Writing memory  [####################################]  100%
+Written 8 bytes to memory ID PSECT at address 0x168
+```
+
+Here is the interpretation of the fields:
+
+```
+00400000 -> start address 0x00004000
+C904     -> 0x4C9 pages of 512-bytes (= 612.5kB)
+01       -> bootable flag
+01       -> image type for the application
+```
+
+Please note the user can write additional partitions by writing
+`image_dir_2/3/4` with the wanted configuration. In case of using the `SPSDK`
+tool, the appropriate offset must be calculated
+
+## Removing SSBL Upgrade Region
+
+The example also offers the possibility to remove SSBL upgrade region, for
+reserving more space for application level.
+
+A new flag `chip_reduce_ssbl_size` is introduced. In order to remove the SSBL
+upgrade region, `chip_reduce_ssbl_size=true` must be provided to the build
+system
+
+The programming method will change:
+
+-   Writing image directory 1 should change to Using DK6Programmer utility from

+    Here is the interpretation of the fields:

+    ```
+    00200000 -> start address 0x00002000
+    D904     -> 0x4D9 pages of 512-bytes (= 620.5kB)
+    01       -> bootable flag
